I'm about to buy heads for my stock bottom end 4.6 2v. Anyone have some for sale?

Thanks
Joe

Yes

No

If boosted just slap some ferrea comp 6000 exhaust valves in it otherwise it comes with excellent springs and all already ready to go as is.

I won't argue that tfs aren't better, its the $1000 difference that is hard to take.

If TFS gains 35rwhp over PPIs then $1000 for 35rwhp is good. Then bigger cams and better cam timing because there’s more PTV clearance. Power all over the rpm range which is unusual for 4.6 cams or most aft. intake manifolds.

People spend $200 on pullies and $225 on a TB for peanut hp.

A PI engine will never make what a tfs head does.

Not sure what you mean? Pi headed engine will never make what tfs topped one does?
